A Study on Protection of Maternal Antibody against Hantavirus in Rats
우영대,--,--,--,--,-- 대한의생명과학회 2005 Biomedical Science Letters Vol.11 No.1
The etiologic agents of haemorragic fever with ranal syndrom (HFRS) in Korea are Hantaan and Seoul virus in the genus Hantavirus, family Bunyaviridae. In order to elucidate the role of maternal immunity to Hantavirus infection in rats, the protective effect of the maternal antibody were studies by using rats experimentally infected with Seoul virus strain HR80-39. Antibody titers of sera and viral antigen against Seoul virus were investigated by indirect immunofluorscence antibody technique (IFA). The dam sera had IFA antibody titers ranging from 1:128 to 1:1,024 after parturition. In fetuses, IFA antibody titers ranged from 1:16 to 1:64 just after birth, increased to peak titers ranged from 1:256 to 1:1,024 in the 2nd week after birth. Challenged newborn rats had IFA antibody titers ranging from 1:64 to 1:1,024 after inoculation. No viral antigen was detected in lungs or other organs of the newborn rats. The maternal antibody to Seoul virus was transferred prenatally through placenta and postnatally via colostrum from immune dams to their offspring. These results demonstrated that maternal antibody to Seoul virus was quite effective in protecting newborn rats against same virus infection.

This paper deals on the Hardware development of 3-D scanning type electronic probe for 3-D measuring machine. 3-D measuring machine usually used in products management, high cost needs for decision measurement. This decision measurement needs more and more caused by local factory becomes automation. This research used LVDT scanning type sensor which this sensor can be accurate in short length and also used in compact space, there of LVDT measuring range ±1.25[mm]and resolution 0.1[㎛]have been complished. In the future more develop the electronic control parts and software, this probe will be used in the world widely with power.

The objective of this paper is to study experimentally anisotropically consolidated clay which are subjected to repeated loading, and to include in this experimentally study the measurement of pore water pressures, stress - strain, pore water pressure - strain and equilibrium line. For this study the undrained triaxial test is performed by using compression failure, cycled at failure, 2-WAY, non-failure equilibrium test.

The ranula is a form of mucocele which specifically occurs in the floor of the mouth. The ranula is classfied into simple ranula and plunging ranula according to the mechanism of development such as the salivary duct obstruction or the extravasation. Clinically this lesion develops as a slowly enlarging painless, fluctuant mass on one side of the floor of the mouth and the mucosa may have a translucent bluish color. An 8-month-old male infant visited our hospital with the chief complaint of the left submandibular swelling and the mass on the floor of the mouth. We tentatively diagnosed a simple ranula. The marsupialization was performed but the sign and the symptom did not subside, so we took the MRI. By the MRI we diagnosed a plunging ranula and excised the sublingual gland via the intraoral approach. The correct diagnosis is essential for the most effective treatment, which is the excision of the sublingual gland.

Neurofibroma is benign neurogenic tumor originated from nerve tissue-Schwann cell, fibroblast, perineural cell. They have no sexual predirection and generally no symptom. Neurofibroma is classified to solitary type and multiple type and is rare in oral resion. They located in soft tissue of tongue, lip, palate and oral mucosa in form of sessile and pedunculated mass and are rare intraosseous region. In solitary type, complete excision is the choice of treatment due to their rare recurrence rate. In multiple type, the same is choice of treatment but bas some difficulty of plastic problem, bleeding

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.
